Osmosis and Diffusion Terms and definitions
Do Now Copy the following in your science journal Use the whole page Word: Diffusion Definition: Example: Picture: Word: Osmosis Definition: Example: Picture:
Osmosis and Diffusion 1. Diffusion - the process by which molecules spread from areas of high concentration, to areas of low concentration
Osmosis and Diffusion 1. Diffusion eventually spreading out evenly into the available space
Pair Share See if you and your partner can come up with 3 real world examples of diffusion Write one of them (or another classmate’s) in your Freyer’s model and sketch a picture
Osmosis and Diffusion Several factors can affect the rate of diffusion…… One such factor is temperature Higher temperatures tend to increase the rate of diffusion
Osmosis and Diffusion 2. Solutes- a substance dissolved in fluid Ex: Salt is a solute, when it is concentrated inside or outside the cell, it will draw the water in its direction This is also why you get thirsty after eating something salty
Osmosis and Diffusion 3. Solvent - is a liquid, solid, or gas that dissolves another solid, liquid, or gaseous solute resulting in a solution
Osmosis and Diffusion Osmosis A specialized type of diffusion is the movement of a solvent (frequently water) through a semi-permeable membrane Osmosis is a type of a process where a fluid passes through a semipermeable membrane and moves from an area where a solute is present in low concentrations to an area where a solute is present in a higher concentration
Osmosis and Diffusion In the real world………. In humans, osmosis occurs in the kidneys to recover the water from waste materials of the body. The kidneys regulate the concentration of water in the blood plasma. Kidney dialysis What other organs/organelles are responsible for filtering (allowing some things through but not others)?
Osmosis and Diffusion In the real world In plants, osmosis occurs for example at root hairs, allowing the uptake of water from the soil.
Osmosis Ameoba Sisters: Osmosis and Diffusion Osmosis is a type of a process where a fluid passes through a semi-permeable membrane, from a higher concentration of water to a lower concentration of water
Ameoba Sisters Answers
Do Now Write down two examples of real life diffusion in you science journal Or else…
Gummy Bear Lab Before you look at your gummy bear, make sure you have: Written your prediction on the first page of your lab packet Recorded your measurements on the second page Height and width should be in millimeters Weight should be in grams Once you get your gummy bear, complete steps 8 and 9 of the Procedure
Do percent problems last Millimeters Grams
Do Now Fill in the blanks (write out the sentences): Diffusion occurs when particles flow from an area of ____concentration to ____concentration Osmosis occurs when ______ is involved, and it passes through a semi-______ barrier.

Diffusion Webquest Go to the following website hallihanscienceclass. weebly. com/ Click on the Diffusion Webquest near the bottom of the page This will allow you to click on the links for questions 2, 3, 4, 8 If you finish early, go back and check over/finish your gummy bear lab
Do Now Draw a picture to represent the following: Diffusion Osmosis Semi-permeable barrier Concentration (high and low)
Osmosis Lab After you place the baggie in the cup, answer questions 6 -7
Matching Match the 8 words with their corresponding definition/examples Raise your hand when you think you’re done
Osmosis Lab Answer the rest of the questions, and if you finish early, complete your four pictures from the beginning of class
Osmosis and Diffusion Hypotonic Solutions: contain a low concentration of solute (more water) When a cell is placed in a hypotonic solution, the water diffuses into the cell, causing the cell to swell Hint : po boy sandwich
Osmosis and Diffusion Hypertonic Solutions: contain a high concentration of solute (less water) When a cell is placed in a hypertonic solution, the water diffuses out of the cell, causing the cell to shrivel Hint: Hyper kids
Osmosis and Diffusion Isotonic Solutions: contain the same concentration of solute ( equal amounts of water) When a cell is placed in an isotonic solution, the water diffuses into and out of the cell at the same rate The fluid that surrounds the body cells is isotonic
